Is there a differ

Here is how I use com.sun.javafx.scene.control.skin.CustomColorDialog:

public Color showColorDialog(String title, Color initialColor) {

CountDownLatch countDownLatch = new CountDownLatch(1);

ObjectHolder selectedColorHolder = new ObjectHolder<>();

Platform.runLater(new Runnable() {
    @Override
    public void run() {
    try {
        final CustomColorDialog customColorDialog = new CustomColorDialog(getWindow());
        customColorDialog.setCurrentColor(initialColor);

        // remove save button
        VBox controllBox = (VBox) customColorDialog.getChildren().get(1);
        HBox buttonBox = (HBox) controllBox.getChildren().get(2);
        buttonBox.getChildren().remove(0);

        Runnable saveUseRunnable = new Runnable() {
        @Override
        public void run() {
            try {
            Field customColorPropertyField = CustomColorDialog.class
                .getDeclaredField("customColorProperty"); //$NON-NLS-1$
            customColorPropertyField.setAccessible(true);
            @SuppressWarnings("unchecked")
            ObjectProperty customColorPropertyValue = (ObjectProperty) customColorPropertyField
                .get(customColorDialog);
            selectedColorHolder.setObject(customColorPropertyValue.getValue());
            } catch (NoSuchFieldException | IllegalArgumentException | IllegalAccessException e) {
            LOG.error(e, e);
            }
        }
        };

        customColorDialog.setOnUse(saveUseRunnable);

        customColorDialog.setOnHidden(new EventHandler() {
        @Override
        public void handle(WindowEvent event) {
            countDownLatch.countDown();
        }
        });

        Field dialogField = CustomColorDialog.class.getDeclaredField("dialog"); //$NON-NLS-1$
        dialogField.setAccessible(true);
        Stage dialog = (Stage) dialogField.get(customColorDialog);

        dialog.setTitle(title);
        customColorDialog.show();
        dialog.centerOnScreen();
    } catch (Exception e) {
        LOG.error(e, e);
        countDownLatch.countDown();
    }
    }
});

try {
    countDownLatch.await();
} catch (InterruptedException e) {
    LOG.error(e, e);
}

return selectedColorHolder.getObject();
}
